'Knockout' is Lil Wayne's fourth single off his rock album 'Rebirth.' The song has a pop-y guitar-driven melody (think Blink-182) under Lil Wayne's auto-toned vocals, and get this: Nicki Minaj sings! Yes, the leading lady in the rap world reveals a sweet husky voice...until she delivers crushing lines in the bridge: "You better not start duckin' / Oh yo / Head on with the blow / Lo-look out in the crowd / And everybody's yellin' no/ Grab him by the locks / And give us a good box / The head of the below the belt / I wanna give him a good tock."
'Knockout' follows 'Drop the World' featuring Eminem. Tune into AOL Radio's New Hip Hop First station to listen to the new track.
